SSgt Reckless was a pack horse during the Korean war, and she carried recoil-less rifles, ammunition and supplies to Marines. Nothing too unusual about that, lots of animals got pressed into doing pack chores in many wars, but this horse did something more, during the battle for a location called Outpost Vegas, this mare made 51 trips up and down the hill; on the way up she carried ammunition, and on the way down she carried wounded soldiers.

What was so amazing? Well she made every one of those trips through enemy fire on her own! No one leading her!
